15CrMo boiler tube is a low alloy heat-resistant steel with excellent high temperature strength and oxidation resistance, suitable for manufacturing boilers and other equipment used under high temperature and high pressure conditions. It has good corrosion resistance and is suitable for acidic, alkaline and salt corrosion environments. Anti-corrosion treatment is still required during use to extend its service life.
GB 5310 15CrMo Seamless Alloy Tube is mainly used for key components such as superheater tubes, reheater tubes, gas guide tubes, main steam pipes, etc. of high-pressure and ultra-high-pressure boilers.
